c sharp中的加密密码和用户名。 [英] encryption password and user name in c sharp.

问题描述

我想用c sharp加密密码和用户名。

解决方案

你好朋友，



试试这个..它适用于密码...







byte [] newByte =加密（txtPwd.Text）;



public static byte [] Encrypt（string plainText）

{

string passPhrase =Bl @@ dB @nk; //可以是任何字符串

string saltValue =EmerGENcy; //可以是任何字符串

string hashAlgorithm =SHA1; //可以是MD5

int passwordIterations = 2; //可以是任意数字

string initVector =@ 1B2c3D4e5F6g7H8; //必须是16个字节

int keySize = 256; //可以是192或128

byte [] initVectorBytes = Encoding.ASCII.GetBytes（initVector）;

byte [] saltValueBytes = Encoding.ASCII.GetBytes（saltValue） ;

byte [] plainTextBytes = Encoding.UTF8.GetBytes（plainText）;

PasswordDeriveBytes password = new PasswordDeriveBytes（passPhrase，saltValueBytes，hashAlgorithm，passwordIterations）;

byte [] keyBytes = password.GetBytes（keySize / 8）;

RijndaelManaged symmetricKey = new RijndaelManaged（）;

symmetricKey.Mode = CipherMode.CBC;

ICryptoTransform encryptor = symmetricKey.CreateEncryptor（keyBytes，initVectorBytes）;

MemoryStream memoryStream = new MemoryStream（）;

CryptoStream cryptoStream = new CryptoStream（ memoryStream，encryptor，CryptoStreamMode.Write）; cryptoStream.Write（plainTextBytes，0，plainTextBytes.Length）;

cryptoStream.FlushFinalBlock（）;

byte [] cipherTextBytes = memoryStream.ToArray（）;

memoryStream.Close（）;

cryptoStream.Close（）;

// string cipherText = Convert.ToBase64String（cipherTextBytes）;

返回cipherTextBytes;

}

Nuget Package中还有Bcrypt https://www.nuget.org/packages/Bcrypt-Official/ [ ^ ]，您可以使用它们。这很简单，并且还有用于加密和解密的有用功能。



谢谢

I want to encrypt password and user name in c sharp.

解决方案

Hello friend,

Try this.. it will work for password...



byte[] newByte = Encrypt(txtPwd.Text);

public static byte[] Encrypt(string plainText)
{
string passPhrase = "Bl@@dB@nk"; // can be any string
string saltValue = "EmerGENcy"; // can be any string
string hashAlgorithm = "SHA1"; // can be "MD5"
int passwordIterations = 2; // can be any number
string initVector = "@1B2c3D4e5F6g7H8"; // must be 16 bytes
int keySize = 256; // can be 192 or 128
byte[] initVectorBytes = Encoding.ASCII.GetBytes(initVector);
byte[] saltValueBytes = Encoding.ASCII.GetBytes(saltValue);
byte[] plainTextBytes = Encoding.UTF8.GetBytes(plainText);
PasswordDeriveBytes password = new PasswordDeriveBytes(passPhrase, saltValueBytes, hashAlgorithm, passwordIterations);
byte[] keyBytes = password.GetBytes(keySize / 8);
RijndaelManaged symmetricKey = new RijndaelManaged();
symmetricKey.Mode = CipherMode.CBC;
ICryptoTransform encryptor = symmetricKey.CreateEncryptor(keyBytes, initVectorBytes);
MemoryStream memoryStream = new MemoryStream();
CryptoStream cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write); cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length);
cryptoStream.FlushFinalBlock();
byte[] cipherTextBytes = memoryStream.ToArray();
memoryStream.Close();
cryptoStream.Close();
//string cipherText = Convert.ToBase64String(cipherTextBytes);
return cipherTextBytes;
}

There is also Bcrypt available in the Nuget Packagehttps://www.nuget.org/packages/Bcrypt-Official/[^], you can use them. This is easy and has useful functions for encrypt and decrypt as well.
